Introducing the Universal Cart and more ways to help you shop

We’re building the foundation for agentic commerce, with updates including a new intelligent cart that brings superpowers to your shopping.

People shop across Google more than a billion times a day, powered by advanced AI and the Shopping Graph — the world’s most comprehensive catalog of over 60 billion product listings. As agentic technology advances, shopping has the opportunity to become even more powerful, intelligent and fun.

We’ve been building the foundation for agentic commerce — from a common language for agents with Universal Commerce Protocol (UCP) to the payments infrastructure to make agentic checkout seamless. Today at Google I/O 2026, we introduced the next step that brings this all together: the new Universal Cart.

Introducing an intelligent, proactive shopping cart

Universal Cart is an intelligent shopping cart and your new hub for shopping on Google. It works across merchants and across services, so you can add things to your cart while you’re browsing Search, chatting with Gemini, watching YouTube or even reading your Gmail.

The moment you add a product to your cart, it gets to work in the background — finding deals and price drops, giving you insights on price history and alerting you when an item is back in stock. It all runs on our Gemini models, so your cart gets even smarter as the models improve.

Universal Cart also uses intelligent reasoning to anticipate your needs and help solve problems before they arise. Say you’re building your first custom PC and add a few parts from several retailers to your cart. Your cart will proactively flag any product incompatibilities and suggest alternatives. Since the cart was built on Google Wallet, it understands your payment method perks, loyalty information and merchant offers so it can help you choose. This lets you quickly find opportunities for hidden savings or points without having to remember them yourself.

When you’re ready to buy, UCP makes checkout from your cart super smooth. You can check out with Google Pay in just a few taps with many of your favorite brands, or transfer your items to the merchant’s site to complete your purchase. You can try these select checkout features soon across merchants like Nike, Sephora, Target, Ulta Beauty, Walmart, Wayfair and Shopify merchants such as Fenty and Steve Madden. No matter which way you buy, the brand stays the merchant of record.

Universal Cart is rolling out across Search and the Gemini app in the U.S. this summer, with YouTube and Gmail to follow.

Expanding the Universal Commerce Protocol’s impact

Since we co-developed the Universal Commerce Protocol with retail leaders earlier this year, the industry has rallied around this common language in an incredible way. Recently, we welcomed several new tech partners to help steer this open standard.

Building on that momentum, we’re expanding our UCP-powered checkout experience on Google to Canada and Australia in the coming months and later to the U.K. UCP is also coming to YouTube in the U.S., and to even more verticals, starting soon with hotel booking and local food delivery.

Scaling secure agentic purchases

We created the Agent Payments Protocol (AP2) to help agents make secure payments on your behalf, with boundaries and accountability to give you peace of mind. AP2 lets you set strict guardrails for agentic payment transactions. Just tell your agent the specific brands and products you want and how much it can spend, and the agent only makes the purchase when your criteria are met.

Under the hood, AP2 creates a transparent, verifiable link between you, the merchant and the payment processor and uses privacy preserving technology to keep your data safe. Tamper-proof digital mandates ensure the agent is always acting on your behalf, giving you a permanent digital paper trail. So, if you ever need to make a return, you and the merchant are looking at the same record. We’ll begin bringing AP2 to Google products in the coming months, starting with Gemini Spark.

While the full potential of agentic commerce is still unfolding, we’ve been laying the building blocks for this future for years. Now with Universal Cart, we’re excited to put that foundation to work for shoppers. Check out more ways Search is using the power of agents to help you ask even more of your questions.

Google's Universal Cart Can Help You Avoid PC Building Missteps | PCMag

That is the headline of Google’s major e-commerce announcement from Google I/O 2026!

Google is shifting from a search engine that merely finds products to an agentic commerce hub that helps you manage, track, and purchase them across different apps.

Here is a breakdown of what Universal Cart is and the other shopping updates announced alongside it:

🛒 1. What is the Universal Cart?

Instead of having fifty open tabs and separate shopping carts for different websites, Universal Cart acts as a single, persistent, intelligent hub.

Cross-App Saving: You can add products to this single cart from any corner of the Google ecosystem—whether you are looking at Google Search, chatting with Gemini, watching a review on YouTube, or opening a promotional email in Gmail.
Background Deal Hunting: The moment an item enters your cart, Gemini works in the background using Google’s Shopping Graph (which maps over 60 billion product listings). It automatically tracks price drops, surfaces historical pricing data, and sends you back-in-stock alerts.
Loyalty & Perk Maximization: Because it links with your Google Wallet, the cart automatically calculates hidden savings, credit card perks, and merchant loyalty points so you don’t have to remember them.

The “Smart” Twist — Compatibility Checks:

The cart doesn’t just hold items; it reasons about them. For example, if you are buying parts to build a custom PC or pieces for a home patio set from different retailers, Universal Cart will actively flag if two parts are incompatible and suggest alternatives before you check out.

💳 2. Seamless & Autonomous Checkout

Google is introducing two major underlying systems to make buying things through an AI much smoother and safer:

Universal Commerce Protocol (UCP): This creates a unified language between AI agents and retailers. You can check out in a few taps directly using Google Pay across major supported brands (like Target, Walmart, Nike, Sephora, Wayfair, and Shopify stores), or smoothly transfer the entire cart over to the merchant’s site.
Agent Payments Protocol (AP2): This update allows you to securely authorize an AI agent (starting soon with Gemini Spark) to make purchases on your behalf within strict spending limits. It uses tamper-proof digital “Mandates” to leave a permanent audit trail, ensuring you stay completely in control of your funds.

📅 When and Where is it Launching?

US Rollout: Universal Cart is starting its rollout in the US this summer (2026), appearing first in Google Search and the Gemini app, with YouTube and Gmail integrations following later in the year.
Global Expansion: The underlying Universal Commerce Protocol (UCP) checkout is expanding beyond the US to Canada and Australia in the coming months, with the UK next in line.
New Verticals: Google plans to expand this protocol beyond retail goods into hotel bookings and local food delivery soon.
